Another object of our invention 1s to providea simple and eflicient device for the pur se stated. T- ese and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

front. A'dov'e tailed slide 73 is carried b the projection'71. A lever 74 has mounted in it a shaft 75 carrying a'pinion 76 which meshes with rack for reciprocating the slide 73. The slide has mounted thereon a shaft 77, this shaft serves as. a bearingfor the carrier or table that is to receive the electrotype upon which tool 19 operates. The foregoing details are described herein solely for the purpose ofexplanation and may be varied in accordance with the general accepted practice.

The shaft 77 has revolubly mounted u on it, a collar 30 carrying a worm wheel 31t at maybe rotatably actuated bymeans of a worm 32 controlled by a hand wheel 33. The collar 30 is provided with a slot 34. The carrier 35 is mounted upon the shaft 77 and is retained in position thereon by means of a coilar or spacer 36 and a suitable nut 37 mounted upon the'end of the shaft 77.

The carrier 35 comprises a tubular shaft 38 having formed thereon pairs of right and left; hand threads. As shown herein the tube shaft in enlar ed at its center, the -central portion thereo being set off from the reduced end portions thereof by shoulders 39 and 40. The. shoulders serve as abutments for limiting the inward movement of the threaded sleeves 41 and 42' mounted upon the ends of the tube shaft 38.. Flanges 43 and 44 are formed at the extreme ends of the tube shaft. The flange .44 carries a lug 45 that may enter the slot 34- whereby to effect unitary movement of the carrier and the collar 30 by means of the hand wheel or-crank 33. The flange 44 also serves as an abutment for engagement on the collar 30. The flange 43 serves as an abutment for the collar 36. The central and portion of the tube shaft 38, has mounted on it threaded sleeves 46 and 47. Each of the threaded sleeves .41, 42, 46 and 47 has pivotally mounted .on it a pluralityoflinks48. Thelinks48extending from sleeves 41 and 46 have pivotal mount- 7 ingsu bars49,apluralityofwhichbars' axten concentritnlly about the tube shaft 38. Eachbar49isalsopivotallyeo gtznxair'of links 48, and which huh-48 from threaded sleeves 42 and 47. Fmmtheforegoingit willbe evidmtthat relative movement of the tube eral bars 49. The outer surfaces of the 'bars are provided with elongated dove tailed of the threaded sleeves for locking the threaded sleeves in various positions.

Eachof the threaded sleeves comprises a hub portion 55 provided with radially extending lugs 56 that are spaced from one another for providing recesses for the reception of the ends of links 48. A ring 57 is provided with radially extending spaced lugs 58 adapted to register with the lugs 56, the recesses between adjacent lugs 58 reg1stering with the-recesses provided between lugs 56. The adjacent faces of the lugs 56 and 58 are provided with complementary groovesfor the reception of wires 59 or the like for providing pivotal mountings on the sleeves for the links 48. Each of the hub portions of the sleeves are provided with threads for engagement by threaded lockin rings 60 that are mounted upon the hu lis and secure the rings 57 in engagement upon the lugs 56. The pivotal mountings of the links 48 upon the bars 49 may be effected in any suitable manner, for example by providing pairs of depending flanges 61 various adjusted upon the inner face of the bars 49 and between which airs of lugs suitable pins 62 may extend. The endsof the links 48 would be dis osed between the flanges 61.

In ig. 4 the sleeves are shown in dotted line to indicate substantially the limits to which said sleeves may be brought together for expanding or extending the bars 49.

B reference to Figs. 2 and 3 it will be rea ily evident that byexpanding and contracting the bars 49, the bars 49 may be .moved to various radii. It therefore follows that eleetrotypes of various curvatures may be mounted expanded or contracted within the limits established by the toggle structure effected by means of the links, threaded sleeves and tubular shaft. Electrotypes of various arcs may be accommodated by so as to dispose the dogs adjacent the edges 4 of the electrotype whereu on the set screws 53 would be employed or clamping the electrotype upon the bars 49.

upon any carrier that may be:

adjusting the dogs to the sleeve 30 by he means of the lug 45 and the slot 44 wherebly duced outwardly of the enlarged portion thereof and being provided with right and left hand threads, the portions of the shaft having threads extending in a common direction being spaced by one of theportions of the shaft having threads extending in the opposite direction, a threaded sleeve mounted on each threaded portion of the shaft, links eachhaving a pivotal mountingv upon one of the sleeves, a plurality of bars extending in parallelism with the 'axis of the shaft, the links mounted on the sleeves disposed 'on adjacent enlarged and reduced portions of the shafts eachhaving an end mounted pivotally upon individual bars-in axial alignment, and each bar having a pivotal mounting upon a pair of links associate'd'with each set of sleeves.

2. In a device of the class described the combination of a tube shaft having an'enlarged central portion, the said central portion being provided with oppositely extending threads, the shaft portions extending from the said central portion being reduced and provided with threads extending in directions opposite to thethreads-on the adjacent enlargedportion, a pair of threaded sleeves associated with each enlarged and reduced portion ofthe shaft, pairs of links associated with each set of sleeves, one link of each pair having a mounting on one sleeve of one set and the other link having a pivotal mounting on the other sleeve of the same set, and bars each having a pivotal mounting on' a pair of links associated with the links of each pair havingaligned axes at their places of mounting upon the bars.

In a device of the class described the combination. of a shaft rovided with two sets of opposed right amfleft hand threads, the portlons of the shaft having threads ex tending in a common direction being spaced by one of the portions of the shaft having threads extending in the opposite direction a threaded sleeve mounted on each threade portion of the shaft, links each having a pivotal mountingupon one of the sleeves, a plurality of bars extending in parallelism with the axis of the shaft, the links mounted on the sleeves at opposite ends of the shaft mg palredfand each link of each pair hav ng an and mounted pivotally upon the same bar, and each but having a pivotal mounting upon? a pair of links associated with each set of sleeves. 4. In a device .of'the-class described the com ination of two sets of rings, each set "for accommodating various elecset and to simultaneously separate the rings of each set of 'rings, dependent upon the direction of movement of the shaft relative to the rings, a plurality of pairs of links,

each ring of each set being connected-with its associated ring by a plurality of pairs each link of each pair of links having an end pivotally connected to a ring of one set of rings, each link of each pair of links having its said pivotal mounting on a different ring of its associated pair of rings, and bars extending between the pairs of links connected with different sets of rings,
